PHP Custom Class Fsocket The method of simulating post or GET request _php tips

This example describes the PHP custom class Fsocket method for simulating post or get requests. Share to everyone for your reference. Specifically as follows:

zsocket.class.php files are as follows:

<?php class Zsocket {* * * Init/Private Function _fsockopen ($host, $port, & $errno, & $errstr, $timeout
  {$ip = @gethostbyname ($host);
  $s = @socket_create (af_inet, sock_stream, 0);
   if (Socket_set_nonblock ($s)) {$r = @socket_connect ($s, $ip, $port);
    if ($r | | socket_last_error () = = einprogress) {$errno = einprogress;
   return $s;
  }} $errno = Socket_last_error ($s);
  $errstr = Socket_strerror ($errno);
  Socket_close ($s);
 return false;
  * * * Set cookies/Private function _setcookie ($cookie) {$_cookies = explode (";", $cookie);
  $_tmp = explode ("=", $_cookies[0]);
  Setcookie ($_tmp[0], $_tmp[1]);
 return $_cookies;
  * * Get Return header content/Private Function _getdataheader (& $fp,& $reHeader,& $cookies) {$maxlen = 0;
   while (!feof ($fp)) {$line = Fgets ($fp, 1024);
   if (substr ($line, 0,) = = ' Set-cookie: ') {$cookies [] = $this->_setcookie (substr ($line, 12));}
   $reHeader. = $line; if (substr ($line, 0,) = = ' CoNtent-length: ') {$maxlen = Intval (substr ($line, 16,-2));
  if ($line = = "\ r \ n" | | $line = = "") break;
 return $maxlen;
  * * Get Return Data body content/Private Function _getdatabody (& $fp, $maxlen) {$reData = "";
   while (!feof ($fp)) {$line = Fgets ($fp, $maxlen + 1);
   $reData. = $line;
   if (strlen ($line) < $maxlen) $maxlen = $maxlen-strlen ($line);
  else break;
 return $reData; /* * Set and return header content to send/Public function get_headerinfo ($host, $type = ' get ', $file = '/', $params =array (), $head =array (),

  }else if (is_string ($params)) {$_params = UrlEncode ($params); foreach ($cookies as $key => $value) {$_cookies. = ";". $key. "

  \ r \ n "; if ($_cookies!= ') $header. = "Cookie:. $_cookies."
  \ r \ n "; /* foreach ($_server as $name => $value) {if (substr ($name, 0, 5) = = ' Http_ ' && $name!= ' Http_host ') {$ header. = Str_replace (', '-', Ucwords (Strtolower) (Str_replace (' _ ', ', substr ($name, 5))). ". $value."
   \ r \ n ";
  } */$header. = "connection:close\r\n\r\n"; $header. = $_params. "
  \ r \ n ";
 return $header; * * * Send, and return the result Array/Public function Get_senddata ($host, $port=80, $header = ') {if (function_exists (' Fsockopen ')) {$fp = Fsockopen ($host, $port, $errno, $ERRSTR, 10);
  }else if (function_exists (' Pfsockopen ')) {$fp = Pfsockopen ($host, $port, $errno, $ERRSTR, 10);
  }else if (function_exists (' stream_socket_client ')) {$fp = Stream_socket_client ($host. ': '. $port, $errno, $ERRSTR, 10);
  }else{$fp = $this->_fsockopen ($host, $port, $errno, $ERRSTR, 10);
  $fp = Fsockopen ($host, $port, $errno, $ERRSTR, 10); if (! $fp) return Array (' header ' => ', ' Data ' => $errstr. "
  ---> ". $errno, ' cookie ' => ');
  $reHeader = $reData = "";
  $cookies = Array ();
  Fputs ($fp, $header);
  $maxlen = $this->_getdataheader ($fp, $reHeader, $cookies);
  $reData = $this->_getdatabody ($fp, $maxlen);
  Fclose ($FP);
 Return Array (' header ' => $reHeader, ' data ' => $reData, ' cookie ' => $cookies); }
}

The demo code is as follows:

$host = ' www.jb51.net ';
$port = ' no ';
$type = ' POST ';
$file = '/';
$params = ';
Include_once (' include/zsocket.class.php '); Include
$zsk = new Zsocket ();
$header = $zsk->get_headerinfo ($host, $type, $file, $params);
$data = $zsk->get_senddata ($host, $port, $header);
/* echo "<!--\ r \ n";
Print_r ($header);
Print_r ($data);
echo "-->\r\n";
* *
var_dump ($header);
Var_dump ($data);
